Basilskite, do call the chef before you go and talk to him / her. 2pm on a saturday may be a good time, but it depends always on how busy they expect to be. Restaurants are heading into the busiest time of year, with the various holidays and Christmas approaching, so you may want to plan your visit. This also demonstrates that you are sensitive to their schedule. I used to hate it when job applicants called me during service, and I'm still sensitive to never call a chef at that time unless he or she asks me to. One option would be to target specific operations which are of interest to you, do your research as to who is who in it, and then approach them and explain to them why you want to work for them, and nobody else. Much more effective than just "looking for a job". Once you have made contact, offer to do a "working interview" where they get to try you out for a day - or evening, and you get to try them, too. This works for some operations, however some large organizations are a bit leery because of liability. I'd check into it, anyway. Good luck, and let us know how it goes.
