Hi! I might be too late?!
I ate out at ASK! last night and had Spaghetti Pomodorou. Their pasta is cooked from dry not fresh so that is free. I allowed for olive oil (2 x B choices on Green) and the Mozarella (A Choice). I don't think there would be many additional Syns on top. You can have any of their pasta dishes in a half size with the rest of the plate as salad which could be a good way to go if you want a starter too?
If you go on their website, they have an offer of buy one main course and get the other for £2.50. Sadly, I only saw this when I got home!
Hope this helps. If not, what did you have lol?
