*This is an updated review now that I have visited it in person.* This is the first fast food place I’ve tried in Uruguay that isn’t from a big American chain and I loved it. The burger and fries I got were delicious! The burger was similar to ,but better than, a McDonald’s cheeseburger. The fries were different than McDonald’s ones but equally as good. I ordered through PedidosYa to try it, and now I’ve visited it too. Before my visit, I downloaded the app to get coupons. I used the coupon for a double ham and cheddar junior meal at the price of 239 pesos. It’s a very good deal. Inside the place is very large and nice. It’s definitely newer. You order on the first floor and there is plenty of seating. The second level has additional seating. They also offer free wifi and I saw many people on their laptops taking advantage of it. I think you have to get the password from one of the employees. I definitely recommend giving Mostaza a try.

I love the ambiance, food is good as well 👍

Nice place

Very good hamburger but very little fries

Very good ambience. Nice designed interior with lot of space to sit and eat. A must visit place for Burger lovers. They have an app available in playstore . Which have coupons, incase you are looking for offer prices. Burgers are big and combo is priced at a decent rate. Covid protocols are considered and seat are well arranged. Service is good.

Pretty neat prices, really good food. Would've liked a bit of a bigger burger for that price but it wasn't such a big deal.

A good experience, I did buy the wrong food, but quality of chicken nuggets was worth the mistake.

Went there for a quick burger to check out the general taste of this fast food restaurant. Got a double cheeseburger and was positively surprised from the smoky meaty taste of the patty. Burger comes nicely assembled and keep it's shape throughout eating it. The restaurant looks very clean and the design and atmosphere is very pleasant.

Good selection and good quality. Prices are ok. Ambiance is a tad better than other franchise burger places.

Execellent service and food was served hot and well portioned

Much better than the usual fast food place, you get more out of your money's worth as well.
