If you are departing from a field located below a Class B airspace, are you still restricted to 200 kts? I know that there is a stipulation that state that if your minimum safe speed is faster than 200 kts, you can fly that, but what about a normal departure?

Yes & Yes.

Incidentally, ATC assignments that exceed that restriction and are accepted could result in a possible violation too.

200 knots or clean maneuver speed whichever is higher.

91.117, says 200 KIAS under the bravo shelf.

Sec. 91.117 — Aircraft speed.
(a) Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 m.p.h.).

(b) Unless otherwise authorized or required by ATC, no person may operate an aircraft at or below 2,500 feet above the surface within 4 nautical miles of the primary airport of a Class C or Class D airspace area at an indicated airspeed of more than 200 knots (230 mph.). This paragraph (b) does not apply to any operations within a Class B airspace area. Such operations shall comply with paragraph (a) of this section.

(c) No person may operate an aircraft in the airspace underlying a Class B airspace area designated for an airport or in a VFR corridor designated through such a Class B airspace area, at an indicated airspeed of more than 200 knots (230 mph).

(d) If the minimum safe airspeed for any particular operation is greater than the maximum speed prescribed in this section, the aircraft may be operated at that minimum speed.

I'd be curious to have anyone describe a routine situation where a modern civil aircraft could not be safely operated at 3000 MSL at or less than 200 KIAS.

The point is you don't have to put flaps out to comply with this restriction, nor with the 250kts below 10,000 ft restriction. If I'm over 250 below 10,000, I'll let ATC know as a courtesy to give them a heads up for separation. So yes, any 737-400,800,900 would have to put flaps out to fly at 200. I used to fly the MD-80 and occasionally the clean maneuver speed would be 255-260 when you were heavy. Obviously heavy jets need to exceed 250 to stay clean on departure as well.
