Limousines are usually rented by the hour, so the time spent at the restaurant may be included in the price. However, many companies will make concessions if you explain that it's just a trip to a wedding without a special budget. Sometimes it's better to rent a limo only for the most important moments, such as the ride to the registry office and the restaurant. I've had experience renting limo hire London and companies there often offer packages or short trips to avoid waiting fees. You can also arrange pickup directly from the restaurant, which is cheaper.
