I've bought dinner at Dunston's Steakhouse in Dallas, TX. They accept Bitcoin LN and chain via BTC Pay Server. Even better, I think they actually hold the Bitcoin and understand the mission.

I found it on the website: https://btcmap.org/map

I'm loving this map website for finding places that accept Bitcoin. However, I've found many of the places on it don't actually accept it, so use it with caution.
