For both restaurants, word is Mid-July to August. All depends on when they release the actual opening dates and all that fun stuff.
Note: The Mid-July to August is when reservations may open, both restaurants are slated to open sometime in Sept-Oct (no offical word yet, other than "Fall 2010", which could mean mid-September as well, even if it's not "offically" fall, it's still the start of the fall season).
