To celebrate seven years in business, The Hay Merchant is throwing a crawfish boil, bringing in some Louisiana beer and tapping eight to 10 craft beers that have been tucked away in the cellar for just such an occasion. The Hay Merchant is open until midnight on Wednesdays. However, the crawfish and special beers are only available until sold out, so get there as close to the 4 p.m. opening time as you can.
