Sorry! I'm all thumbs! I was going to say that there are some great suggestions above.
Don't forget all the other senses apart from taste, though:
ATMOSPHERE
Attractively-laid table; lighting; good company, possibly music.
SMELL
Great cooking smells whet the appetite as does the smell of the food when it arrives at the table.
SIGHT
The way the food is presented can make a big difference. The type of plates, dishes, glasses etc together with the colours of the different ingredients can make a big impression.
TASTE
The key to it all, of course. Consistency and tenderness/crispness combine to make a meal memorable.
Choose a selections of wines to go with the different courses (for example, a crisp white with the starter, a good red with the meat course, a dessert wine with the sweet) bearing in mind that the taste of the wine changes as you eat the food.
SOUND
Probably not appropriate in this case, but sound can be fun (e.g. sizzling of hot-plates when restaurants serve certain oriental or Asian dishes).
Quality is more important than quantity!
Bon app�tit!
