Welcome, mikeoverthepond! I think the adjustment will get better with time. I felt that I really hit my stride here about 3-4 years in actually.
I know it isn't Dunkin Donuts (I prefer them too) but I hear tell of some places to get Krispy Kreme donuts here & there in the UK.
Also, do you mean Spanish food, or like Tex-Mex food? My husband & I have traveled to Spain quite a bit & he makes a mean plate of Spanish food, from ingredients that are quite readily sourced here. Also there are tapas restaurants, etc.
Tex-Mex, on the other hand, is my speciality and takes a little more research to source ingredients or substitutions, but it can be done!
Welcome again & all the best!
