I’m 60. I constantly use Levitra 10mg. I was doing an experiment. Take a pill and run for 30 minutes. My intimacy lasts 1 hour (while without the drug it lasts 5-10 minutes). If you don’t run, erection gets worse. If you starve for half a day, you’ll have erection but no pleasure. A significant factor is stimulation, i.e. the woman must seduce you. Don’t take the Levitra (Vardenafil HCI) more than 5 times a week, as it can negatively affect your heart. It would be good if the pills would be cheaper, as they’re too expensive for a pensioner.

“My passion for the British seasons shines through the menu at this unique little restaurant tucked away on our little street in Mayfair. After a substantial refurbishment in April 2019, No.5 Social delivers a warm and welcoming atmosphere whilst retaining simplicity and elegance.”

Welcome to No.5 Social

Quite literally across the street from flagship restaurant Pollen Street Social, Jason Atherton and head chef Kostas Papathanasiou bring the best of British produce to the table.

Menu highlights will include; Copper maran poached egg, wild mushrooms, brioche and truffle emulsion; Poached Hebridean halibut, roasted violet artichokes and sunflower; Herdwick lamb chop and braised neck, crushed Jersey royal potato, peas, mint and cucumber.


Kostas Papathanasiou - Head Chef

Kostas, originally from Greece, studied in London before starting his career in The Fat Duck restaurant in Bray where he worked and built up his skills for 6 years. From here, he spent a year and a half in Singapore working as Head Pastry Chef in The Kitchen at Bacchanalia.

On his return to London he joined the team at The Ledbury in Notting Hill as Chef de Partie. It was 3 years after this that Kostas joined The Social Company and worked at Pollen Street Social alongside Jason Atherton and Dale Bainbridge as Senior Sous Chef before moving across the road and taking the lead here at No.5 Social.


Led by the turning British seasons and working closely with producers to deliver the freshest ingredients, allowing you to explore the natural landscape in each dish.


Recently refurbish, Jason Atherton has created a modern, intimate space, featuring a neutral colour palette with accents of earth tones, pale pinks and deep blues, creating a warm and welcoming atmosphere.
