I have NEVER been here when the weather was warm enough to go out onto the fabled patio. Am I missing something? How awesome can a patio be? I'm sure I'll make my way there eventually, but for now I can only imagine the wonders said outdoor patio holds.
Round Corner Cantina is pretty good indoors too. My relationship with Round Corner Cantina is simple & pure. If I'm breathing, then I want tacos. They have good tacos, and they'll bring tacos to my table in a friendly fashion.
They've got good cocktails, good beer, and I think they are reasonably priced. They have fun drink specials.
I like coming here for food, I don't know if I'd come here to hang out because I feel like I'm too old for their crowd ...although their lack of lighting could help me blend in. In the one back room, its really dark.
So if you're on a date with someone who is not exactly a feast for the eyes, take them here. There's tacos and it's dark. Your situation will immediately be improved 100%.
tip: this place is ALWAYS packed. If you LOVE to sit during happy hour, I recommend getting here early to stake your claim to a seat.
