Nice chill place. Good beer selection. Lots of local stuff on draft. Also have a good amount of Bottles/Cans to either drink on site ($2 fee) or take them to go. You can also do Growler fills. Check their website for current draft selection. They have a small patio in front. When the weather is nice it's great to sit out. Shaded so you won't bake in the TX sun. They also have a couple Tabs inside with sports and ChiveTV.

We love this place for their great selection of beers on tap as well as the run club that happens every Monday night. The Bear Creek Run Club meets each week to have a pint or two after a 2 mile run around Bear Creek Park nearby. What’s on Tap is the perfect spot to drop in for really good craft beer. They’ll always be sure to have a beer (or cider) you’ll enjoy. Good indoor and outdoor area, I always recommend What’s on Tap to our friends.

Excellent craft beer seller. Friendly staff team, always happy to advise on the available drafts. Happy to provide tasters if most beers (not the “red” ones, which are strong). I cannot fault this place. Regina is fab, and Matthew. They have a small patio area at the front which is comfortable (I just avoid evening there as the mosquitoes are crazy in this part of Keller but to be fair they are also just bad because it is the south!)

Great responsive staff, friendly fast service and good selection with a wide variety of styles and breweries represented here. You can order soft pretzels with dipping sauce or grab some chips. I Fratelli pizza delivers here for free too, no kitchen though. There’s a handful of ciders and wines as well.

Cool, low key spot brewery that has great customer service and good beer. Definitely recommend for a chill night out.

Love this place! Casual atmosphere, always a great selection of beers and friendly beer tender ( I'm pointing at YOU, T2!). Also, a small outdoor seating area that is great for sipping and people watching!

The best place to try fancy beer. Nice, clean, friendly.

Regina, Matt and staff are wicked awesome here, plus super delicious craft beer selection on draft and in cans & bottles for beer-to-go. #nicetacker 🍻🍻

Great little tap room...very friendly staff... fantastic rotating selection. Recommend!

Clean, nice, organized rows. Great selection. Competitive prices. Friendly, and helpful staff

Great blend of local and regional craft beer, friendly and knowledgeable staff, no food yet but will be tied to the great FNG Eats next door. Growlers available, reasonable prices, can expect good tap rotation. A welcome addition to the area!

Great selection of beer from around the globe and across town. Fast friendly bar tenders. Fun times on trivia nights. Great Detroit style pizza frozen, but still tastes great.

Love the place!! They have 35 different variety of microbrewery!! Amazing place. You can order the food at the bar, but the food gets delivered from a nearby place called Boca 31!! Yummy food and lively place!!! Enjoy!!

THIS PLACE has always had a great selection, and awesome growler prices! Jayce was a genius 👏

Good vibe and running club. The free beer tomorrow sign got me 🙃 i actually told my fiance we should go there tomorrow...

Just a small typical tap house. Nothing super interesting on tap, standard fair. They do have an interesting selection of packaged beer. They do offer a pretzel and a little Detroit style pizza. Patio is super small but nice.

Great place. Lots of craft beer choices. Friendly beertenders. Trivia on Thursday nights.

Neat little place in the Keller Town Square area. Was really surprised to find as many beers on tap as I did. Had no idea this place existed but was recommended by a friend. With several plates on the wall at the Fort Worth flying saucer, I came here after a charity fun run with this same friend and was really amazed to see the eclectic bunch of small releases and bigger names in the microbrew industry. We were here to get a beer, not enjoy any food. Really didn't see a whole lot of food options but then again we really weren't looking. Google seems to recommend items as if they do have food. If I lived down the street from this place, I would probably find myself here a few times a night. Those who live in the condos above who are beer aficionados have a nice little place within walking distance. This was my first and only visit, so I don't really know how often the taps rotate. Neat little place, and will definitely be back.

What's on Tap used to be an inviting local spot for beer and socializing, over time this spot has fallen off its previous standing, they overcharge for some of their "craft" beer and rotate beers frequently. Food offerings are terrible, unless you want heat and eat pizza. Should you decide to carry on a political conversation with someone at the bar, be prepared to have the beer guy tell you that political discussions are not allowed. Or at least frowned upon. Some of the servers, Tim, Jason, and Erica are great, the rest are just wallpaper. After all, you can train a monkey to pour a beer. A much better option is The Local, plenty of options for watching your favorite team from the SEC, Big XII, etc. A much better option is The Local.

This is a must visit for terrific craft beers on tap, new selections offered regularly, terrific atmosphere and service. This is a great spot to have a delicious beer and hang out - highly recommend!
