Oh that does look good. What wine is worth ordering?
Also, port. Too much choice and no idea.
My recommendation is slightly different from andrewc, that is, unless you know what you are ordering, max out at €5 euro a bottle and don't be afraid of the 2 - 3 € stuff. The white I linked to above is extraordinarily nice, much fruitier and fuller than the normal vinho verde and a personal favourite when I discovered Moncao, cycling through during their wine festival week. Duoro is very sound for reds, especially if you want to spend more money on a bottle, and Dao for satisfying quaffing. I don't think you will go far wrong with any of their wines, the prices you see are those you find in the supermarkets in Portugal for everyday wines.
Port? Where to start. If you haven't, try a white port, they are drier and make a great aperitif. Colehita port is another gem rarely seen outside portugal - think of it as a Tawny on steroids. My own go-to for port tends to be LBV for convenience and price, and the cheapest
LBV on the site looks to be a bargain.
Have a look at Majestic Portugal
selection - the white I was talking about is at least as good as the Cazas Novas @ £10.
