I came here Sunday August 4th for dinner. I had the lasagna, 2 friends had the pizza and 2 others in my group did not eat. It was an average meal. Fast forward to 10 hours later, early Monday morning, I woke up to a churning stomach, went to the restroom where I proceeded to spew out red tomato sauce from BOTH ends. It was a terrible morning. Both of my friends who had pizza woke up and had considerable GI discomfort all morning. They weren't as bad as me, but they were not enjoying life. Essentially, our Monday drive home was miserable. The two who did not eat were fine. I called the restaurant Wednesday evening, after I felt better to let them know I had possibly gotten food poisoning from their restaurant. The manager immediately doubted me -- blaming the sickness on too much drinking (absurd). I had maybe 5 beers the entirety of Sunday. So unless a server shoved a bottle up where the sun doesn't shine before serving me, I have a hard time blaming it on the beer. Not to mention, I'm in my 30's...I went to college...I am fairly familiar with alcohol sickness and hangovers. This was not that. I explained to the manager that there were 5 of us and we all ate at the same places all weekend, except for Sunday night, when only 3 of us ate...the same 3 that got sick. The manager proceeded to proclaim that you get food poisoning 72 hours after ingestion. I had to look that up...it's not true. Why he would lie? I have no idea. He just really didn't seem to even being open to the notion that his restaurant got me sick. Regardless, I didn't call asking for anything...I only called to inform them of the events and how my friends and I narrowed it down to their establishment. The manager asked for my contact info and told me their general manager would get back to me in 24 hours. It has been 5 days. Not expecting that phone call...and I'm not expecting to ever eat at a Wolfgang Puke establishment again.
