You'll get fantastic Mexican street eats with the usual [Rick] Bayless upgrades at this River North counter-serve (with a Wicker Park sequel) where grub like tremendous tortas, amazing churros and incredible breakfast items succeed in offering fast food without compromising quality; the small space can have long lines (and be a mob scene at lunch), and the ordering process can be kind of weird, but all is forgiven considering the affordable tabs; P.S. the new locale is larger, full-service and offers wine and cocktails too (both have beer).
