Part vegetarian market, part banh mi shop and part fast-casual restaurant, Duy's Sandwiches is a humble, family-run hole-in-the-wall on the side of a strip mall at Wilcrest and Bellaire, where it easily goes unnoticed. But step into this hidden gem, and you'll find wholesome, healthy, affordable cuisine (most everything is in the $5 to $8 range), as well as fabulous vegan banh mi. The banh mi, just $3.25 each, are fantastic. Oblong rolls of crisped French bread are filled to the brim with cucumber, pickled carrot and daikon, cilantro, and jalapeño, and a choice of faux meat filling. The popular No. 1 special is filled with a Vietnamese sausage made of corn, soy and peas that tastes as if it could be real meat (it's vegan). Other things to try include the vegan curry and the noodle soups, which include pho and bun rieu. There are also small containers of freshly prepared takeout dishes such as fried tofu and sautéed vegetables for just $5. Cash only and totally worth it.
