We will have some indoor lunches. Do I need to lug my external flash with me? I have D90.

I've actually started using my external flash a lot during the day, mostly as fill flash. As ukcatfan said, you have to set it for high speed sync so that you can take advantage of the faster shutter speeds during the day. (otherwise, without turning on high speed sync on your flash, your camera's stuck at 1/250 sec or slower, possibly overexposing your photo because of the slower shutter speed)
As for indoor lunches, I would definitely use the external flash. Here's a photo I took at during lunch at Les Chefs de France at Epcot:
I set the camera exposure for the background / ambient light, and slightly underexposed it. I set the external flash to TTL to light Remy, the Chef rat from Ratatouille. I don't think I could have balanced the foreground with the ambient light
without using an external flash.
This camera / external flash set-up & settings are also especially useful if you're having character dining for your indoor lunches.
I'm certainly no expert at using flash (my wife can attest to that...she's been blinded by all my "test shots"). But I've been reading and re-reading and re-reading about how to use an external flash. I've tried pouring through the Strobist Web site (
strobist.blogspot.com/2006/03/lighting-101.html). All this flash information is slowly starting to sink in. Over the past year, I've really started bringing my external flash with me every time I have my camera, and I've found it to be a surprisingly useful tool, even during daytime.
