Will 3rd or 4th Terry Black's. It's not cheap, though. I think they raised their prices during covid. FWIW if it's a weekday and you swing by between 4pm and 4:15pm it's pretty dead recently and there's no line (with actual parking spaces available). I'll occasionally hit it after work and it's nice to get something that good without standing around forever.
2nd or 3rd The Range as well. If they're from England then it does touristy gun stuff pretty well. It's a boutique kinda joint as opposed to the dive bar feel a lot of indoor ranges have. They will probably find it more "accessible" if they're not gun people.
Phoebe's on 1st and Oltof does the traditional American bacon-and-eggs thing well. It's like 5oz of slab bacon. Kinda seems like they might want to try that if they're from England. Plus it circumvents the breakfast taco fight that's inevitable since there's so many people from San Antonio posting here.
