Pub food and drinks help

I'm out on Saturday and have been saving syns this week so I can treat myself a little more

I am planning on having the one course and a few drinks, I know what the best drinks are diet tonic or coke with spirits... however does anyone know an average for syns in cocktails? In case they take my fancy

Also I have picked the best meal from the menu, however I'm still not 100% sure how many syns to count it as, can anyone advise me

Salmon fillet, hot smoked over hops, sauteed potatoes and buttered green beans.

I know I could ask for the beans without butter as well, but how much should I count for the butter if not? Also how much for the potatoes?

Oh and I will have about 70 syns to spare

I'm not sure about the food options but I would choose extra dry martini (vermouth) as the measure is 50ml for only 2.5 syns - bargain . Obviously mix with diet lemonade/ sprite etc.
The bianco and rosso are 4 syns for 50ml so still better than spirits but not as good!
