I've got no experience or knowledge of retail leases, but wouldn't the people behind Beulah have had the lease for a month or so before opening, in order to fit out the unit to get it ready for use? In which case they might be ready to hand the shop over pretty soon.
At a guess the current tennants are losing money on the restaurant, so they'll probably want to get shot of the lease asap. So is it possible they might have come to some arrangement with the landlord to get out of the lease early?
Obviously, this is pure speculation, born of a very quiet afternoon at work.
Whatever happens, it would be great to have a thriving new bar and restaurant on this side of the tracks. Hope it does well. It's a shame Beulah didn't take off.
