For those that may not know, Twitter geotags you to a general area where your tweet came from as seen in the photo above. Their tweet came from an area of San Francisco called Cow Hollow. Now, this doesn't pinpoint a restaurant or a specific place, but it does put them in a small geographic area.
What's interesting is what is located within 3 minutes driving distance from the heart of Cow Hollow:
That's right, LucasFilm. LucasArts is also on this campus.
So I thought, well, maybe their publisher just decided to have dinner with them and they coincidentally went there...except that it's on the other side of town from the GDC and several other locations Spark mentioned they had been.
Spark tweeted:
Spark Unlimited @sparkunlimited
The W is the hotel bar to meet up and drink up. It is rough sometimes doing business. ;)
Spark Unlimited @sparkunlimited
Dinner is over. Heading to the Infusion Lounge now.
The Infusion Lounge, The W Hotel, and the Moscone Convention Center(where GDC is being held) are all within 2 blocks of each other and a 20 minute drive away from LucasArts and where they had dinner. This of course is not definitive proof that Spark Unlimited had dinner with LucasArts. However, when companies attend out of town conventions, they tend to stay very close to the hotel or the convention location and away from areas that may only be familiar to someone that might live and work in the city.
***UPDATE***:
So from the info above, Spark went to dinner with their publisher(whomever it may be) from the restaurant within 3 mins. driving distance of LucasArts to the Infusion Lounge across town after dinner.
Guess what?
LucasArts hosted their GDC party at the Infusion Lounge that night.
