If you have a kitchen island, put 3 pendants above it. Looks fantastic and gives superb illumination.

Avoid at all costs the dreaded oyster light! They are UGLY and do not in general give good lighting.

For my kitchen, I used commercial grade gimbles at key spots (eg above the sink, above the stove etc). That decision was absolutely perfect, I highly recommend it.

A lot of people don't put in dimmers in their kitchens but I would suggest it. Kitchen lighting is very often too bright and dimmers allows you to tone it down.

I've worked with a few interior designers who have out LED strips on kitchen walls and undercabinets. Worked really well.

Try pendants over the middle of the kitchen. You can use three identical ones, or 3 similiar ones but different sizes.

Putting multiple spotlights in the middle of the kitchen ceiling works really well. By trial and error I have seen that 6 or 7 is a very good number.

The kitchen is a bit of a boring room, so I decided to make a statement and put a huge chandelier in the middle. Gave it a lot of mood and atmosphere, and also provides lots of lighting too.

Under-cabinet lights are nopw becoming very common.

LED strips on the undersice of cabinets and inside cupboards works well.

Make sure that if you have a pantry, it is well lit. I have seen lots of pantries that have one light - often shadowed by the person in there!
