When I'm wrong, I'm wrong, so here's an update to correct prior misperceptions.
Previously, I had posted (see link) about a weird experience with the crust at Joe Squared. Not only was my theory about the possible cause wrong, but subsequent visits have shown that my experience of the weird metallic taste was an aberration. I figured that if I posted this update on that thread, nobody would see it, so I'm reposting and referring back to the prior thread.
After going back to gather more data points, I can now enthusiastically say that this is a pizza worth giving a try. The pizza at Joe Squared doesn't fit neatly into any niche, so it's hard to make comparisons, other than to say that they have their own vision of what a pizza can be, and it's worth checking out. I'd put it in the same category as Matthew's and Iggie's, in that they are among the few standout pizzas in the Baltimore area, rising well above the general mediocrity of most pizza in this area. Note for the NYC-style fans - this is NOT an NYC-style pizza, but check it out anyway. You might like it!
I'd also suggest checking out the risotto. I've only tried the spinach so far, but that was tasty enough that I will be exploring that section of the Joe Squared menu as well.
Again, mea culpa, and let this serve as a reminder that one can have an "off" experience at even the best places. If your instincts tell you that the restaurant is on the right track, give them a second chance and go back! Also, don't be afraid to provide feedback. The good places do want to find and fix anything that isn't working, and they can't do that unless they know that a problem has occured.
I should also note that I've had off-list correspondence with Joe, who was very interested in not only correcting my mistaken hypothesis, but in trying to deduce what went wrong on the crust that I commented on, so as to prevent any future mishaps. I really appreciate him taking the time to pursue the matter, rather than dismiss my concerns or write me off as an ill-informed idiot.
