There doesn't really seem to be a place to grab an apres drink at Rockwood hotel. The Iwaki Lounge doesn't open till 5pm and the vending machines are beer free. Your only choice is the souvenir shop with their resort prices and there isn't much choice for nibbles. Definitely BYO.
The tuning station at Rockwood is pretty basic. Just a table, stands and a screwdriver. If you need waxing done you can drop it overnight at the ski rental counter in the gondola station.
Nice wall art at Rockwood. There are snowboards and skis donated by past champions.
Iga menchi katsu or minced squid cutlets is one of Aomori's specialties and you can try it at Rockwood's buffet.
The bar in the corner of the dining hall serves local Aomori sake, beers, sochu and wine.
