I'm moving to Edinburgh from San Diego (where I've always lived) for a year to attend the university. Two questions, which are minor but have been weighing heavily on my mind:

1. What is the weather like in September? Since I own no cold weather clothes, I'm planning on buying almost everything there. But will warm-ish California clothes be ok for the first month I'm there so long as I have a good coat?

2. I LOVE Mexican food, and will go crazy without it. I read another post mentioning Gringo Bill's- is that good? Are there any restaurants in Edinburgh with authentic mexican food? Do grocery stores carry enchilada sauce/tortillas/mexican seasonings, or will i need to have it shipped to me?

Thanks a ton, this site is amazing.

p.s.- I'm planning on experiencing and enjoying the local food and culture; however, everyone gets homesick after awhile!
