The Nook is a basement cafeteria near King and Spadina. I've had two sandwiches from there. The last one was a pesto chicken. I thought it might be relatively healthy; the only sin ingredient being cheese. OMG! A TON of mayo for the sauce, plus butter for the panini. It was so fattening I had a stomachache for the rest of the day and I couldn't eat much else. Plus, there was a motherload of salt. I got the salt tremors and have avoided sodium today.
I don't usually complain publicly about a restaurant but I can honestly say it was the most unhealthy thing I've eaten in years.
