I have just tried the early bird menu and am amazed at the value. Two courses for just over £10. What is nice is to see most of the italian old favourites covered on the fixed price option including pizza, pasta, and meat dishes. The portion sizes were excellent and the food was bubbling hot - extra points! Quite often such menus are positioned such that customers need order extras to make the bill up. To their credit San Marco even let you have your garlic bread starter alongside your main meal. This means full marks for value especially when given in addition to an inclusive drink to accompany your two courses.
What you will need to contend with is an often lack of any staff to meet and greet. I seem to find that you need walk to the bar before anyone really notices that you are there. Beware if you are a party of two - you may find your table is very near the kitchen or uncomfortably close to the table next to you. The service is polite but sometimes takes some effort to catch the eye if your server. The decor is clearly dated, some of the chairs are quite worn and the tables are draped in plastic table cloths - however, you cannot go here without meaning in mind at all times just how cheap it is. Overall, whilst its probably not a place to bring someone to impress them - it is excellent for an informal weekday dinner.
