I think a more appropriate review would be 3.5 stars but tbqh I'm not sure if there's a half star feature on here (somebody hmu if you can help a sister out).
Overall I had a very pleasant experience at La Botana. It's different from other Mexican restaurants in Fountain Hills so a change of pace is always a plus. They have a salsa bar which is awesome and all the salsas are delish. You order up front, receive a number, and then there are staff members around who bus/serve (kind of like a Wildflower/Panera kind of service). The food was very good and it's also supes vegetarian friendly.
The reason La Botana doesn't get five stars from me is because the service is very slow but frankly I think it has less to do with the servers themselves and more to do with the fact that there aren't enough of them. Seemed like they needed more people - I think I spotted a total of 4 and only one bartender on a very busy Saturday afternoon. It's right across from the park (sit on the patio if you can!) so it's going to be hoppin' on the weekends.
I will be back and will gladly update to five stars if we could beef up the service a little bit, otherwise I give La Botana a solid thumbs up.
