Well I used to go to the Mars Bar several times for drinks. It is a cozy little dive. They supposedly have decent gyros here. Well one such gyro has put me out for a whole day with severe food poisoning. I had to leave early from work because running to the restroom every 15 minutes isn't the best situation for an office. I know 100% that it is from the gyro with the timing of me eating the sandwich at around 9:00 PM at night and then of course 9-10 hours later I wake up nauseous. So far I've been sick for 14 hours now today and it still is rough.
Never again. You can take your chance on this place if you want but if you're unlucky like me you may get some nasty lamb meat that will ruin the following day with excruciating pain.
