Rio Viejo restaurant interior seating area

★★★★★

This place will definitely become a Worcester staple, located right in downtown, the inside is beautiful, staff is warm and welcoming. I sat down at the bar, grabbed a water (which tasted like clean filtered water even without a lemon) they welcomed me, they gave me some complementary chips and salsa. The salsa was delicious, definitely house made. I ordered the Rio Chimichanga, came to me in 10-15 minutes it was delicious. I highly recommend this place, I will be back. The family next to me ordered cocktails which looked amazing and had order the churros for Desert which I will absolutely get next time. Also, I'm a big tequila aficionado and they have a very wide array of Tequilas and Mezcals.

Came last night and we were blown away. We especially were grateful for your meatless part of the menu. Our friends picked your restaurant and we were so excited that it accommodated vegans. THANK YOU!!! I got the meatless burrito and it was incredible. I took off the sour cream and cheese and i was so happy the waitress got it right. As a vegan, I cannot tell you how many times my food comes out wrong and your staff got it right. The guacamole was the best I have ever had. The band was seriously the best. Such a great atmosphere and experience and we will definitely be back.

This place looks absolutely beautiful! Great place to watch sporting events with big tvs going across the back of the bar. Has a variety of different beers on tap. I was greeted by Tee who was very hospitable. She recommended the steak burrito and Lalo tequila. Both were great recommendations. If you haven’t tried definitely give this place a try. Great pregame spot before Woo Sox games or any events in downtown Worcester.
