Excellent Margarita's. Yummy Fajitas. Great for Tex Mex in the area. Chips are good too. That's about it.

Eating here is a real experience. The decor is totally Mexico /Southwestern and so you feel like you have been transported elsewhere. What fun! The service is very good and while you are waiting, there are great chips and salsa on the table. The baskets of chips keep disappearing and being replaced by the eagle-eyed wait staff. The food is... More

I really love this restaurant, my only issue is their lack of vegetarian options. Most of their dishes (even cheese based ones) are all served with sauces that contain meat. If you are a strict vegetarian be sure to ask. They have excellent made to order guacamole and chips. The frozen sangria is to die for!!! Yummy

This is a great place for lunch. From the moment you walk in until you leave it's an experience. I've seen commercials for it and decided to give it a try. Best servers; best tasting foods; many, many choices; they fast which works when you're going to lunch from work; you are in and out, feeling wonderful in less than... More

Wife and I have loved going to Uncle Julio's, we have frequented the Dallas, TX, and old Bethesda, MD sites long ago. I recall we had a friend that worked as a waitress one night in the early 90's when Bush showed up to eat. For some reason he dropped his knife and she rushed to bring him another knife... More

Uncle Julio's is a solid choice if you want a good plentiful meal. If it's nice out- sit outside and enjoy the view. Like most chain restaurants- food was solidly good, lots of choices, and good service. Rio itself is such a fantastic place - so this place e benefits from the overall atmosphere. It's always crowded - perhaps because... More

There is no point in reserving a table for a group if they will make you wait for more than an hour. We were supposed to have a surprise party for a friend and instead of having him come and see us all there seated at a table, we were outside waiting and waiting for a table. People came out...

I had dinner at this place eating at the large bar on my own on Sunday 30th October. As soon as I sat down the bar tender came over and asked if I wanted to see the menu. On handing me the menu she also presented me with a huge bowl of tortilla chips with tomato salsa as a free... More

They have a good menu... I love their dessert selection as well. Every time we go there we are lucky to be just two... There is always a long wait for parties larger than two
