I was in Corpus Christi years ago. The info book in the hotel showed local bars and restaurants. Saw one called 'The Republic of Texas Bar and Grille'.. sounded like a good place to get a burger and a beer..
Me and my entourage all dressed in jeans and t-shirts went there.. Place turned out to be a rather upscale restaurant. Hostess looked at us kinda funny and asked if we had a reservation.. They seated us anyway (we were the only non-suits in the place).. had a great meal and a couple drinks.. and $800 later we were out..
