Yeah a combo for $23 wouldn't sell well IMO not unless it was for TS. You'd have people wondering why they are paying that at that place but $24 for fried chicken at 50s Prime Time or at Skipper Canteen (yeah they are fried vs smoked but you get my point).
Now I do agree with your last comment. I'm not expecting stellar amazing BBQ but it'll likely be good enough but it's not because of the price point even if it was higher I still would have the same expectations.
I'm also glad it's at that price point because the beer alone will have the price tag getting up there
