Visually atmosphere very nice. Unfortunately every surface is hard and ceilings very high. Put a few tables with loud excited kids or adults having a good loud time, not saying people shouldn't enjoy themselves - I say party on, however the noise can become unbearable. If you can, sit outside on the large covered patio. Service acceptable but not outstanding. There were multiple servers at the ready to get you what you need if your server becomes MIA for a bit.
Small mango Margarita: fair size for $. Very mild mango flavor. Overall a little weak & watery tasting. Couldn't tell there was ANY alcohol in it. Decent selection of beers per the guys in our party.
Chips and Salsa very good: delicious light, warm & crunchy chips. Mild salsa is very mild and the hot is hot.
Husband had Fajitas Supreme which he said was not very interesting in taste & he likes everything plain. Even the single portion is large and can easily be shared by two especially if you order any appetizers or fill up on chips and drinks. My Carnitas Tapatias was very bland. There were 6 in our party. Their food choices included Fajitas, burritos and something that was stew like served with or in salsa verde. Due to the noise we paid up and went elsewhere for drinks and dessert. Spent most of that time talking about other preferred Mexican restaurants in Cleveland.
Don't think any of us will be rushing back to Tres Potrillos. Sorry. I really wanted to enjoy it.
