I've never particularly appreciated grilled pizza, and after trying the new Gonzo on 13th Street, I'll probably go back, but not for the pizza.
However, the other night I had a tapenade and fig grilled pizza at inside (Jones street between Bleecker and West 4th) that was fabulous. In addition to the two named ingredients, there was also a good pile of arugula and some shaved parmiagiano. I don't know if it was just very good tapenade, or the perfectly ripe figs, but the it was an amazing combination that left me hungry for more (and I had it again at brunch today).
Initially I didn't think much of inside (and as a vegetarian they didn't have too many choices for me), but it's been steadily moving up my list as they have expanded their "bar" menu which has more veg choices. Along with the pizza I had an unusual babaganouj, smoother, lemonier and less smoky than usual, but with some complex flavors that lingered nicely. Also a tomato salad with ricotta fritters that turned out to be very flavorful heirloom tomatoes set off nicely by the crunch of the fritters.
And the chilaquilies at brunch are some of the best I've had in New York - a VERY tasty tomatillo sauce, lots of rajas, and the tortillas were chewy and even a little crunchy rather than soggy (as they were in a dissapointing chilaquile at the otherwise estimable Taqueria do Mexico on Greenwich Ave).
