Tres Rios is a nice addition to the Southside! The place is larger than I expected, with both a bar area and the 'dining room area'. We went on one of the first weekends it was open and it was early on a Saturday night, there were still 4 - 5 other groups there so it was nice to see they are doing steady business. I was ready for higher prices from the other reviews, but for the margarita and the guac and chips, it was well worth it! The guac had great flavor and comes with two bowls, perfect for sharing! The spicy passionfruit margarita was perfect! I've been places where the "spicy margaritas" have no spice - this delivered!
We also ordered the pork belly tacos. They had a nice flavor, but I'm not sure I would get them again. I am excited to go back when I am hungrier and try the Beet tacos - those sounded great!
I'm sure I will be back again for drinks and the guac! Welcome to the Southside, Tres Rios!
