It's a long time since I've flow, and even longer since I've flown a procedure, but the instruction to "Adhere strictly to missed approach procedure due to proximity of final approach RWY 08R Charles-de-Gaulle" would suggest you descend to 700' first. That said, I guess it also depends on your reason for deciding a missed approach is needed at D5.0 LBG and what conversations you're having with ATC at the time.
