Bill Williams Chicken House, Alfred’s Delicatessen, Felix Mexican, Joe Matranga’s, Kaphans, Maxims, One’s A Meal, San Jacinto Inn, Ship Ahoy, Sonny Look’s, Valaiians, Vargos, and Ye Old College Inn from your list.
Not on your list - Pino’s Italian, Antonio’s Flying Pizza, Angelo’s Fisherman’s Warf, Gaido’s location on South Main Street (Big Shrimp and I think a Blue Crab Statues at entrance), Strawberry Patch, Belaire Broiler Burger, Christies Seafood (now oldest open restaurant in Houston), Rudy Lichner’s, The Stables Steak House, Shakey’s Pizza Parlor and Original Antiones for Po Boys. There are more, but for time sake.
Side note - I worked at Look’s Sirloin Inn on South Main as a busboy in like 1968~1971. When the Homebuilders convention and OTC were in town place was packed 5:00 until 12;00. Would get 10% of waiter’s tips and that would be about $20 a night. Good pay for a 15 year old in 1968 working for $1.25 /hour plus tips.
