If your experience with Tex-Mex-style queso is limited to bubbling pots of processed American cheese laced with canned chilies, you might find the 'Bob Armstrong' version at Javelina (119 East 18th Street, 212-539-0202) somewhat paradigm-altering. On the menu, the Bob reads like typical nacho toppings, apropos for something you're about to dip corn chips into: choose a queso base, and it'll be filled with guacamole, ground beef, pico de gallo, and sour cream. You can pick from a traditional yellow queso, which looks like the Velveeta with which you're familiar, or have a white queso base, which mixes a smooth white cheese with verdant jalapeños and poblanos. Go with the latter -- it eats lightly, with a slight tang. Before you know it, you'll have devoured the bowl.
