Tuesday & Wednesday night is Tapas-only at Kantina, which I am always up for as I enjoy small plates. We ordered a few selections, but none were really that amazing. The food was certainly good quality and had good tastes, but nothing really excited us or knocked our socks off. We had been to Kantina once before a year ago, and had a spotty experience (my dish was far too salty & dessert was tasteless, but my husband's dishes were delicious, so we wanted to give Kantina another try).
Since the tapas didn't really provide us with a memorable dining experience, I doubt we'll be back on our own volition (perhaps if a dinner party is organized here by someone else). However, I suggest people give it a try once to see if you like it. It's certainly high-quality food with very good service.
