I enjoyed a lovely birthday dinner at an oft recommended neighbourhood restaurant last night. All was well until I made a mid-evening trip to the bathroom. When I turned on the light, several large cockroaches scurried out of sight. Yuck! I really like this resto and the food is very good - but this experience was off-putting to say the least. What's the best thing to do? Mention it to our waiter? Follow-up with a phone call?
