I'm normally not a huge fan of the grandma slice -- nobody ever seems to get the dough right, too heavy, too tough, too gummy. But can I rave yet again at the wonderful grandma slice at L&B. Very little cheese. Emphasis on the rich, tangy, slightly sweet sauce which is among the best sauces I've tasted. But the kicker is the crust: crispy bottom, not too thick but great focaccia-like texture. Light yet substantial. And NOT GUMMY.
I'm sure part of it's goodness is that their constant stream of demand means you get your slice right out of the oven, hot and steaming. Vs a place like DeMarco's where it's been sitting around and re-heated.
I'll bring down the venom here, but I prefer the L&B grandma slice over DiFara's, whose crust is too thick for my taste. (Dom's round slice is, of course, still tops.)
PS. L&B sit-down makes incredibly good fried calamari. I could easily eat a couple bowls of this stuff.
