I called to make PS for Big River Grill but was told by the CM that the only BW restaurants that have PS are Flying Fish and Spoodles. We are planning BW for one evening, but don't want to be locked into a time if we don't have to. Is there usually a long wait for a table for 4 at Big River Grill or ESPN between 5:30 -7 p.m. mid-week?
