If by "locals" you mean out-of-college folks, lol okay good luck with that.
One big issue is the amount of upper classmen i.e. those who are actually 21 that move off-campus their junior year. Those who are left are mostly in on-campus apartments. Charter Oak is in the middle of the woods. Hilltop is in the very back of campus nearly in the woods.
But many do end up in Mansfield Apartments or South, which are both easily within walking distance to the bar. The bar will be relying on those two populations (and those who can afford the new apartments in the Center) a lot.
Or, being as big a place as it will be, they may go the Huskies route and take 18+ and just mark the underage kids' hands (if it's like a BWW, they won't need to worry about it; just card people as they approach the bar). I think the size will help encourage kids to go. I remember not wanting to bother with Ted's and Huskies a lot because I knew I'd be packed way in and would be waiting forever to get a drink or anything. Knowing you'll be at least somewhat comfortable makes the walk much more worth it. A very large portion of the campus population from Towers, East, Shippee, Busby, South, Alumni, West, McMahon, and Mansfield are a quick walk or bus ride away.
