There are several mentions of the "Soup Nazi" from Seinfeld here, and that was what Souper Market quickly conjured up in my mind as well. In other words, a tiny storefront with only ten or so barstool seats, serving up little more than an assortment of eight or ten absurdly delicious and fresh-tasting soups in to-go containers. (There are also salads.)
But as others say, there is no verbally-abusive, control-freak "Nazi" at the helm here. Instead, a rather uncommunicative but efficient young fella waited on us behind the counter; he seemed kinda peeved that we and a couple of other customers had interrupted his mid-afternoon kitchen-prep tasks and his Mission of Burma clangor. The soup is served in eight-, twelve-, sixteen-and-even-bigger ounce portions, and it comes with a big slice of almost perfect crusty bread. (The bread almost certainly comes from one of the stalls in the incredible West Side Market across the way.) We tried the Roasted Ratatouille and Tomato Ginger, and I thought both were complex and balanced enough that they could have been hi-jacked from the kitchen of a good high-end restaurant.
Souper Market is yet another example of a dining establishment attaining excellence by focusing like a laser on just one small area of expertise and not getting caught up in trying to do too much.
Top-notch. The only reason I don't go with five stars is the Spartan-ness of it all.
